After being harassed by a man on a flight last week, Sophia Bush decided that enough was enough.

The American actress decided to call out his unacceptable behaviour on Twitter, penning a powerful open letter to the passenger from hell – and offered her harasser some tips on how he should treat a strange woman next time he gets the urge to talk to one.

Addressing her letter to the “random dude” on the plane, Bush wrote: “When you make a woman so visibly uncomfortable that, after you’ve ignored all visual cues to please leave her alone (one word answers, she pulls out a book, pits on a hat, she actually asks you not to speak to her with the tone and words you’re choosing to use) that she finally gets up and moves seats, leave her alone.
